Abstract
In this paper, we present a polarization sensitive frequency diverse array (PSFDA), which benefits both from frequency diverse array (FDA) and polarization sensitive array (PSA), producing angle-range-polarization-dependent beamforming capability. To simultaneously improve the angle, range and polarization resolution, the ℓ1-norm minimization-based sparse constraint and ℓ∞-norm constraint for sidelobe region are further applied. Besides, the performance of the optimal output signal-to-interference-plus-noise ratio (SINR) is analyzed for such a high-dimensional arrays. Numerical results demonstrate that the proposed PSFDA provides both range and polarization resolution as well as target angle estimation. Moreover, the PSFDA virtually increases the array size by exploiting multiple electromagnetic fields at each physical point. In addition, the proposed beamforming method can effectively null interferences, without degrading the array gain for the signals of interest.

2.3 Signal model of polarization sensitive frequency diverse array (PSFDA) For the array constituted by M collocated electromagnetic vector sensor (EMVS), where each vector located at y-axis transmits a different frequency
5 Conclusions In this paper, we formulated the PSFDA signal model and proposed a corresponding beamformer based on the minimum variance for the angle-polarization-range sensitive (MVAPRS), 1-norm minimization and ∞-norm constraint
Summary
Multi-domain signal processing can improve the array performance by exploiting space, time, polarization, frequency resources [1,2,3]. Existing interference suppression approaches can be employed to exploit the angle as well as polarization domain information for polarization sensitive array (PSA), the joint information between range domain and other domains are rarely explored [4]. A new kind of array named frequency diverse array (FDA), which applies a small frequency increment between contiguous two elements, has gained substantial interest [5,6,7,8] This small frequency increment, as compared to the carrier frequency, results in a anglerange-polarization-dependent beampattern [9,10,11,12] that is different from conventional phased-array providing only angle-dependent beampattern and frequency scanning array whose beam pointing angle changes with working.
